Kind of lost on how to apporach this - Array into interger / removing quotes?

[Spring]

Well, In my DB i have user items as follows:

13,12,11,9,27,15,16,22,21,23,24,26,29,30,31,32,33

 

Each ID is a user item that has been imploded to be sent to the DB. Well, I', trying to take them out of the DB now, and I'm having a small problem turning them back into integers.  Here's what I've done.

 

$items = explode(",", $row['user_item_id']);

So I get:

  0 => string '13' (length=2)
  1 => string '12' (length=2)
  2 => string '11' (length=2)
  3 => string '9' (length=1)
  4 => string '27' (length=2)
  5 => string '15' (length=2)
  6 => string '16' (length=2)
  7 => string '22' (length=2)
  8 => string '21' (length=2)
  9 => string '23' (length=2)
  10 => string '24' (length=2)
  11 => string '26' (length=2)
  12 => string '29' (length=2)
  13 => string '30' (length=2)
  14 => string '31' (length=2)
  15 => string '32' (length=2)
  16 => string '33' (length=2)

 

Then I do this:

foreach($items as $item){
				var_dump($item);
				$sql = 'SELECT *
				FROM `MYTABLE`
				WHERE item_tab = '.$tab_id.'
				AND item_id = '.$item.'
				AND item_pose =0';
			}

 

and get this:

string '13' (length=2)

string '12' (length=2)

string '11' (length=2)

string '9' (length=1)

string '27' (length=2)

string '15' (length=2)

string '16' (length=2)

string '22' (length=2)

string '21' (length=2)

string '23' (length=2)

string '24' (length=2)

string '26' (length=2)

string '29' (length=2)

string '30' (length=2)

string '31' (length=2)

string '32' (length=2)

string '33' (length=2)

 

Now, this works how I want it to except, I want a integer value not a string. What would be the best way to approach this?

intval

 

You shouldn't loop queries though, unless you absolutely have to.

 

Since you've stored the values in a comma separated list, rather than in their own rows, you will need to use two queries though. Check out the IN syntax

Highly appreciate the MySQL IN syntax. I have never used it before. I'll try these out and update you accordingly.

removing quote

 

There are no actual quotes around the values in the array. The var_dump simply shows them that way to indicate where the string value being displayed starts and stops.

 

There's no need to do anything with the array values to use them. If you were converting to json, you might need perform a type conversion, but it is not needed for what you are showing in this example.

If you had stored them in their own rows, you could accomplish everything in a SINGLE query. This is the way RDBMS were designed to work

 

SELECT * FROM `MYTABLE` WHERE `item_id` IN (
# Your first query would go here
SELECT `id` FROM `itemstable` WHERE `something` = 'foobar'
) AND `item_tab` = '$tab_id'

 

Saves you for having to verify the results of two queries, and is slightly faster

He didn't say anything about quotes, just that he wanted to values to be integers. Though, in PHP, there isn't a big difference (though a few functions are specific about argument types).

I got it working correctly now! For someone reason, the array didn't have the right keys..anyway,

$sql = 'select * from MYTABLE where item_id IN ('.$items.') AND item_tab = "'.$tab_id.'" AND `item_pose` = 0';

Worked fine!
